Helios@ Digital frequency Shifting Repeaters (FSR) system designed to solve problems of weak mobile signal, which can expand more coverage than RF repeaters and reduce investment for the areas where fiber optic or dedicated cable is not allowed. The Frequency Shifting Repeater system (FSR) consists of two parts: Donor Unit and Remote Unit. The Donor Unit receives the BTS signal via open air radio frequency (RF) transmission or direct couple closed to BTS, then coverts it from the working channel to transmission channel, and transmits the amplified signal to the Remote unit that will reconvert the signal to the working channel and provide signal to the areas where network coverage is inadequate.
As per the method of receiving BTS signal by the Donor Unit, two types of FSR are available:
Cable-Access FSR: to receive BTS signal via a direct coupler closed to the BTS (Recommended)
Wireless-Access FSR: to receive BTS signal via a Donor Antenna
Customized working frequency operating supporting all major cellular frequency bands including 700MHz, 800MHz, 1800MHz, 1900MHz, 2100MHz or 2600MHz.
